Abstract

Background: Mycobacterium Avium Complex (MAC) is a group of related opportunistic pathogens. Previous studies have suggested that residential soils would be a likely source of pulmonary MAC infection. Hence, we analyzed Variable Number of Tandem Repeats (VNTR) patterns of MAC isolates from potted plants surrounded by fences and patients infected with MAC to evaluate the efficacy of fences on infection control.
Methods: Clinical isolates were recovered from the sputum of pulmonary MAC infection patients who had been examined at the Aichi Medical University Hospital. Soil sample was recovered from potted plants surrounded by fences unable to touch by patients and stuffs in patient lobbies. Bacterial species were identified by hsp65 gene. Comparing genotypes of MAC samples were used by Variable Number of Tandem Repeats (VNTR) analysis.
Results: Both clinical samples and soil sample were identified as M. avium subsp. hominissuis determined as hsp65 sequence. Both samples were identified as DQ284765 deposited in Gen Bank. VNTR patterns of clinical sample and soil sample were different.
Conclusion: It was considered that the contact with potted plants is reduced by enclosing fences. Soil infection with MAC might be prevented by enclosing fences the potted plants, further clinical study would be needed.
